Is
it safe?
It is completely safe provided you follow the manufacturers instructions.
TerraQuant also has a an FDA Clearance and CE certification, a mark of
European safety and legal compliance.

How
do I choose between the TQ Pro and theTQ Solo?

More
power in the Terraquant Pro (25,000 mW) provides slightly better penetration
and reduction in treatment times. Please note that penetration and efficacy
is not directly proportional to power. This means that just because you
are using twice the power, you should get twice as good of an effect or
twice the penetration. Body is full of different tissues, cells, etc.
So, linearity and proportionality don't exist in the same format we know
them in math.If first and foremost it is a questions of portability, if
that is essential, then Solo is the winner. If the question is upgradeability
- other emitters, flexibility - frequencies, the the Terraquant Pro is
the choice as it has ports for other emitters.Both units have the 1000-3000Hz
frequency. Its is called the VARiable on the TQsolo and its program #4
on the TerraQuant. Both can use the same probes. Read
the comparison chart for more information.

My condition isn't
listed.
TerraQuant is suitable for pain, wound and skin conditions that can be helped
by the clinical benefits listed on the home page and on this page.

My medical condition
has not been diagnosed. Can I still use TerraQuant?
No. Your doctor must first diagnose your medical condition.

I live in Europe
and I would like to know if it goes with European electricity?Yes, the
power adaptors that come with the equipment are rated 110/240V, which
means that will work all over the world.The
only thing we do is provide a power cord to the adaptor that is the correct
plug style for a specific region/country.

What about Visual Safety?
Person should not look directly at the emitter for more than 30 seconds. TerraQuant
was designed low power requirements for maximum attention to visual safety.
Whether or not you decide to use the safely goggles is largely the matter
of personal preference and comfort.

What happens if something
goes wrong with my device?
TerraQuant comes with a full two-year warranty. Should anything go wrong during
the warranty period, we will either repair or replace your device free of
charge.

I had a breast implant
5 years ago and a nerve was pricked - Neuroma. Can the Terraquant help with
my pain?
Yes. Use the 1000 Hz setting on the TerraQuant of Var setting on the TQSolo
for neuroma. There is no problem with using our laser products over implants,
whether they are metal, plastic, silicone, etc.

What is laser therapy?
For a long time now L.A.S.E.R. (Light Amplification by Stimulated Emission
of Radiation) was an acronym and today a word of common use. The word LASER
is the name of a device that projects intense radiation of the light spectrum.
It produces a beam of light in which high energies can be concentrated. Laser
light has unique physical properties, which no ordinary light has. The unique
properties of coherence and monochromaticity are the key to why laser light
is so effective compared to other kinds of light in pain reduction and healing.
Laser therapy, also known as phototherapy and low level laser therapy, involves
the application of low power coherent light to injuries and lesions to stimulate
healing and reduce pain. It is used to increase the speed, quality and strength
of tissue repair, resolve inflammation and give pain relief. Laser therapy
has been found to offer superior healing and pain relieving effects compared
to other electrotherapeutic modalities such as ultrasound, especially in chronic
problems and in the early stages of acute injuries. Laser therapy is a complete
system of treating muscle, tendon, ligament, connective tissue, bone, nerve,
and dermal tissues in a non-invasive, drug-free modality.

How does it work?
The effects of laser therapy are photochemical in general and with super-pulsed
lasers such as the InSight Series also photomechanical. Photons enter the
tissue and are absorbed in the cells mitochondria and at the cell membrane
by chromophores. These chromophores are photosensitizers that generate reactive
oxygen species following irradiation thereby influencing cellular redox states
and the mitochondrial respiratory chain. Within the mitochondria, the photonic
energy is converted to electromagnetic energy in the form of molecular bonds
in ATP. It is obvious that, in order to interact with the living cell, laser
light has to be absorbed by intracellular chromophores. Cell membrane permeability
increases, which promotes physiological changes to occur. These physiological
changes affect macrophages, fibroblasts, endothelial cells, mast cells, bradykinin,
and nerve conduction rates. The clinical and physiological effects are obtained
by the way in which the tissues absorb laser radiation. This tissue absorption
depends on the wavelength of the beam itself and the power to ensure that
the laser energy reaches the target tissue at the necessary clinical levels.
The use of an improper wavelength laser would not penetrate into the tissue
to reach the target area. Furthermore, even if one has a laser with the proper
wavelength, if the device does not have enough power to drive the energy into
the tissue, the target area may not realize the potential benefits. Each type
of laser emits light at a very specific wavelength which interacts with the
irradiated tissue. It also acts in particular with the chromophores present
in the tissue, but in a different way. A chromophore, intrinsic or extrinsic,
is any substance, colored or clear, which is able to absorb radiation. Among
the endogenous chromophores, water and hemoglobin, nucleic acid and proteins
can be listed. Among the exogenic chromophores we can instead find porphyrins
and hematoporphyrins, which are injected into the organism. These are described
as photosensitizers because they fix themselves to the tissue making it photosensitive
at specific wavelengths.

How deep into the tissue
can laser light penetrate?
The level of tissue penetration by the laser beam depends on its optical characteristics,
as well as on the concentration and depth of the chromophores, which according
to the wavelength are absorbed at different percentages. For instance, water
absorbs almost 100 percent of the laser irradiation at the 10,600 nanometer
wavelength, the wavelength of the CO2 gas laser. That is the reason why this
type of laser wavelength is used in surgical applications. Other factors affecting
the depth of penetration are the technical design of the laser device and
the treatment technique used. There is no exact limit with respect to the
penetration of the light. The laser light gets weaker the further from the
surface it penetrates with a limit at which the light intensity is so low
that no biological effect of the light can be measured. In addition to the
factors mentioned above, the depth of penetration is also contingent on tissue
type, pigmentation and foreign substances on the skin surface. Bone, muscles
and other soft tissues are transparent to certain laser lights, which means
that laser light can safely penetrate these tissues. The radiation in the
visible spectrum, that between 400 and 600 nanometers, is absorbed by the
melanin, while the whole extension of the visible which goes from 420 to 750
nanometers is absorbed by composite tetrapyrrolics. In the infrared, which
covers about 10,000 nanometers of the light spectrum, water is the main chromophore.
Fortunately, there exists a narrow band in the light spectrum where water
is not a highly efficient chromophore, thereby allowing light energy to penetrate
tissue that is rich in water content. This narrow band, which extends approximately
from 600 to 1,200 nanometers, is the so-called therapeutic window. That is
the reason why the therapeutic lasers in the market today have wavelengths
within this therapeutic window. The penetration index is not the same level
throughout the therapeutic window. In fact, lasers in the 600 to 730 nanometers
have less penetration and are suitable for superficial applications such as
in acupuncture.

Pulsed vs. continuous
wave lasers.
In general, lasers diodes are either continuous wave or pulsed. The continuous
wave (CW) diodes emit laser energy for the entire time it is electrically
driven, hence its name. Pulsed diodes emit a radiation impulse with a high
amplitude or intensity and duration of which is typically extremely short
such as 100 to 200 nanoseconds. Continuous wave lasers produce a fixed level
of power during the emission. Although lacking the high peak power of a "true"
or "super" pulsed laser, most continuous wave lasers can be made
to flash a number of times per second to simulate pulse-like rhythms by interrupting
the flow of light rapidly as in turning off and on
a light switch. Pulsed lasers, as the name implies, produce a high power level
impulse of light for a very brief duration for each pulse. It is the high
power level during each pulse that drives the light energy to the target tissue.
Even though the pulse peaks at a high power level there are no thermal effects
in the tissue because the pulses are of extremely short duration. Therefore,
the peak power of a pulsed laser is high compared to its average pulse power.
By using pulsed lasers, one is able to more effectively drive light energy
into the tissue. The laser and electronic technologies required to use pulsed
diodes are more advanced and the diodes themselves are more expensive than
the CW diodes. These are probably the main reasons why over 90% of the therapeutic
lasers in the North American market are low power CW lasers. Some of these
CW lasers provide power on the order of inexpensive laser pointers costing
around $30 USD.

Is laser therapy safe?
Yes. Laser therapy is a drug-free, non invasive therapy with superior healing
ability. However, since lasers produce a high intensity light, one should
never shine the laser directly into the eye. Further it is recommended that
the laser device not be used directly on any neoplasmic tissue. Pregnant patients
should refrain from laser therapy applied directly on the abdomen.

Is laser therapy scientifically
well documented?
There are more than 120 double-blind positive studies confirming the clinical
effects of laser therapy. More than 300 research reports have been published.
Looking at the laser therapy dental literature alone there are over 300
studies. More than 90% of these studies do verify the clinical value of
laser therapy. A review of the research literature of studies that produce
negative results one finds that low dose was the single most significant
factor. By dose is meant the energy of the light delivered to a given
unit area during a treatment session. The energy is measured in joules
and the area in cm2. Assuming that the power of the laser remains constant
during the treatment, the energy of the light will be equal to the power
in watts multiplied by the time in seconds during which the light is emitted.
Therefore, a laser with more power (watts) can deliver the same amount
of energy (joules) in less time. If we use a pulsed laser we can extend
the above statement by saying that a pulsed laser with more average power
(watts) can deliver the same amount of energy (joules) in less time and
at deeper target tissues than continuous wave lasers.

What is hertz
as it relates to Low Level Lasers?
The predefined, controlled breaks in the laser emission, measured by the
number of breaks per second, equals hertz.

What is pulsed electromagnetic
therapy?
Magnetic fields play a key role in biological life. A magnetic field is created
when a conductor is crossed by an electrical current. Magnetic fields arranged
around single conductors are summed in a coil producing a density of magnetic
force lines. If current produced in this way flows in pulses, then a pulsed
magnetic field is created. In the bioenergetic and chemical terms of the organism,
the essential concept of magnetism is not the magnetic load, but the energy-rich
dipole which is surrounded by a magnetic field and whose transformation and
exploitation for the production of energy in the organism is highly significant.
The most important effect from pulsed electromagnetic fields (EMF) therapy
is found on the cellular transmembrane potential (TMP). It is known that damaged
or diseased cells present an abnormally low TMP, up to 80% lower than healthy
cells. This signifies a reduced metabolism, impairment of the electrogenic
sodium-potassium (Na-K) pump activity, and therefore, reduced ATP production.
In a nutshell, the TMP is proportional to the activity of the Na-K pump and
thus to the rate of healing. Healthy cells have TMP voltages of 70 to 100
millivolts. Due to constant stresses of modern life and a toxic environment,
cell voltages tend to drop as we age or due to illness. As the voltage drops,
the cell is unable to maintain a healthy environment for itself. If the electrical
charge of a cell drops to 50, the patient may experience chronic fatigue.
Electromagnetic therapy with the Maxi provides one effective way to affect
healing rates by increasing cellular TMP.

Does laser therapy
cause heat damage or cancer in the tissue?
No. The average powers and the type of light source (non-ionizing) do not
permit heat-damage or carcinogenic (cancer-causing) effects. Due to increased
blood circulation there is sometimes a minimal sensation of warmth locally.

Trends in laser therapy.
Therapeutic lasers are getting better every year. New lasers have entered
the North American markets that provide deeper tissue penetration, higher
power densities and reliable electronics to achieve better clinical outcomes.
The trend has been to increase power density and dose, since these have
been shown to produce better clinical outcomes. In the case of superficial
target tissues, clinicians have several laser options to consider. For
tissue just beyond a few millimeters from the skin surface, underpowered
lasers currently available in North America do not deliver the needed
light energy to the treated tissues that present in patients in a typical
healthcare office.
